[epidemian]

Depends on the definition of "for free".

Depending on where one lives, but many people have access to "free" government services, ranging from roads, education, unemployment security, healthcare, and more. The costs of these services are payed by taxes.

Some "free" services are sustained via donations. Wikipedia is a good example of this.

Some people might say that those are not examples of "for free", because someone is paying for those things, either via taxes or donations. They do have a cost for society. Yes, but in that case then ad-based services are not free either: the advertisers are putting the money to run those services, and the society is also paying a huge cost in thousand of hours of people's lives wasted down the drain, promotion of harmful products, scams, etc.
